In one out of every two years, 20 percent of Bangladesh is inundated. Floods that occur at frequencies of one in 5, 10, 20 and 50 years inundate 30, 37, 43, and 52 percent of the country, respectively. The nation pays a ...

This study was designed to examine in detail the causes of hysteresis (irreversibility) in the adsorption-desorption process' for two herbicides and its impact under field conditions. An effort was made to relate rate, ...

Acid soils are the largest available lands for peanut cultivation expansion in Indonesia. This study was undertaken to determine the effects of lime on peanut growth on an acid soil of West Sumatra. In the first experiment ...

Manganese (Mn) in excess of crop requirements is a serious problem when manganiferous soils become acid, waterlogged or amended with organic materials. We investigated the dynamics of manganese phytotoxicity and tested ...

Field and laboratory experiments to evaluate pH, silicon and phosphorus effects on papaya were conducted on the island of Kauai on an aluminous ferruginous latosol. The main plots were soil pH (5, 6 and 7) attained by ...

Nitrogen, phosphorus and potassium were applied separately from 0 to 1120 kg/ha to upland and lowland taro. A 2 x 2 x 2 N-P-K interaction experiment was also conducted in pots using 0 and 15 grams of each element per plant. ...

In a field experiment the effects of irrigation frequency, S application (pH) and P fertilization on the yields and mineral composition of sugarcane grown under saline conditions were investigated. Sugarcane variety H50-7209 ...

A sugarcane field experiment was carried out to evaluate the effects of a range of K rates (0-1920 Kg/ha) from cane juice stillage (residue from alcohol production) applied broadcast or in the furrow and KCl on cane and ...

Two constraints prevent widespread adoption and application of mechanistic models for predicting solute and water transport in soils and aquifers. They are (a) the high cost and technical difficulty of measuring the transport ...

Simple methods to estimate water extractability and hydraulic conductivity were tested in nine Mollisols, Ultisols and Andisols. A neutron hydroprobe was used to monitor soil water content over depth and time. A method to ...
